Abstract: 1461110 Taping machine MIDLAND ENG & MACHINE CO 30 Dec 1974 [28 Dec 1973] 56044/74 Heading B8G In a hand or foot driven taping machine a member, mounting a pad for supporting a tape end and mounting a tape cutting blade, is cyclically moved along a path between a first position, in which the pad may be moved transversely of the path to press a tensioned tape end against a rotatable body for taping, and a second position in which the blade may be moved transversely of the path to cut tape extending from the pad to the body, the cut tape end being pressed by a retractable wiper on to the body. To tape an electrical coil 45, Fig. 1, wound on a bobbin, an adhesive tape led from spool 50 via rollers 61, 62 has its end 52 retained on a pad 73 by keeper 75, Fig. 6. To start, taping, handle 71 is pivoted upwards on arm 90, carrying rollers 61, 62, so that pad 73 presses the tape against the coil. A hand crank is rotated to rotate the coil and arm 90, biased by spring 95, is pivoted downwards by cam 92 to carry the pad and keeper from the coil, Fig. 7. During the completion of one coil rotation, Fig. 8. handle 71 abuts a stop and is pivoted, with the pivoting of arm 90, so that cutter blade 80 lies adjacent the tape. Handle 83, carried on handle 71, is then raised to cause blade 80 to cut the tape. With further coil rotation, arm 100 is pivoted towards the coil so that wiper 102 presses the tape end on to the coil, arm 100 is pivoted away from the coil, and arm 90 rises to the Fig. 1. position. Two turns of the crank produces two turns of the coil and one turn of cam 92. Change gearing is used between the crank and the coil-supporting shaft. Idler roller 63 produces a slack tape loop so that during the start of winding the tape is not tensioned. Roller 61 is adjustably braked by a spring, and rollers 61, 62 are biased by an internal rotating coil spring to prevent backrotation.

Abstract: 1338566 Metallic films INTERNATIONAL BUSINESS MACHINES CORP 3 Dec 1970 [30 Dec 1969] 57384/70 Heading C7F [Also in Division H1] When a metallic film is deposited on a substrate having a different thermal co-efficient of expansion from the film, the film is doped with one or more alloying additions which interact with defects in the film so that hillock formation on the surface of the film is inhibited when the film and substrate are thermally cycled within a given temperature range. A layer of insulating material is formed on the film e.g. by sputtering the thickness of the layer being such that it would be damaged by the formation of hillocks. If the film is of Al the alloying addition may be selected from Be, Cu, Mg, Si and Th and if the film is of Pb, then Au, Al, Ag, As, Sn, Sb or Si may be added. Suitable substrates include oxidized Si, glass, silicon, monoxide, quartz, mica, sapphire, nitrides, sulphides, carbides alumina and metals. The substrate 2-14 is held in a holder 2-16 and may be heated by a heater 2-18. The film material and the doping material are evaporated from separate crucibles 2-20 and 2-22 either simultaneously or consecutively and the rate of deposition of each material monitored by quartz crystal oscillators 2-28 and 2-30 which change their frequency depending on the amount of metal deposited on quartz crystals 2-29 and 2-31.

Title: Process for the production of alkali metal salts of polycarboxylic acids
Inventor: HARTEL HEINZ
IPC: C08G2/00
Filed: 1966-12-22
Abstract: Alkali metal salts of a polycarboxylic acid are obtained by producing a suspension of a polyaldehyde by polymerizing an a -b -ethylenically unsaturated aldehyde in the presence of a Redox system containing silver nitrate as reducing agent making the suspension alkaline by adding alkali metal ions thereto, and thereafter oxidizing the polyaldehyde by passing oxygen or an oxygen-containing gas through the heated suspension, whereby the desired alkali metal salt of a polycarboxylic acid is produced in solution.  The free polycarboxylic acid may be produced by filtering off from the solution the hydrated silver oxide formed as a result of the suspension being made alkaline, and acidifying the filtrate.
